Being billed for two lines

I moved to Cape Town and app**** for a land line as well as ADSL. After a long back and forth of technicians not pitching for the appointment, a landline was installed, but not ADSL. After another back and forth, another technician came for ADSL, but installed another line. He said he had to do it, but that I have to cancel the prior line at my local Telkom office. I did go and do that.<br> Yet I have been billed for two lines ever since. Have reported this issue on 10210 (after a call of 1 hour), another back and forth between 3 different operators. A couple of days thereafter they informed me that it will be adjusted, however I have once again been billed for two lines.<br> I do not know who to contact any more!
